Resonant Inductive Coupling as a Potential Means for Wireless Power Transfer to Printed Spiral Coil

Abstract: This paper proposes an inductive coupled wireless power transfer system that analyses the relationship between induced voltage and distance of resonating inductance in a printed circuit spiral coils. The resonant frequency produced by the circuit model of the proposed receiving and transmitting coils are analyzed by simulation and laboratory experiment. The outcome of the two results is compared to verify the validity of the proposed inductive coupling system. Experimental measurements are consistent with simulations over a range of frequencies spanning the resonance.
